SPECIFICATION forming part of Letters Patent No. 668,447, elatedFebruary 19, 1901.

Application tiled November 1S, 1900. Serial No. 36,377. (No model.;

T0 @ZZ whom, it may concern:

Be it known that I, AUGUST KREIDT, residing at Indianola, in the countyof Redwillow and State of Nebraska, have invented certain new and usefulImprovements in Leverage- Power Mechanisms, of which the followingis aspecification.

This invention has for its object to provide an improved arrangement oflever mechanism whereby al minimum amount of manually-applied power canbe readily converted into an accumulative force for driving lightmachinery; and the invention consists in the details of construction andpeculiar com bination of parts, all of which will hereinafter be full;7described, and pointed out in the appended claims, reference being hadto the accompanying drawings, in Which- Figurc 1 is a side elevation ofmy improvements. Fig. 2 is a plan View of the front portion thereof.-Fig. 3 is a transverse section taken on the line 3 3 of Fig. 1, and Fig.4 is a perspective view illustrating the peculiar correlation of theseveral lever members in detail.

In the accompanying drawings, 1 indicates a suitable supporting-frame,comprising the side bars l, the cross-bars 1b, and the supporting-legs1C.

2 2 designate standards projected up from the bars 1a near the frontend, iu which is jonrnaled a crank-shaft 3, having a central crankmember 3, and its ends are projected laterally beyond the standards 2 2,as clearly shown in Fig. 2, by reference to which it will be noticedthat on one end of the shaft `3 is mounted a drive-pulley 4, which inpractice may be belted with a drive-shaft (not shown) of the machine ormachines to be driven.

Upon the shaft 3, preferably adjacent the pulley 4, is mounted anadjustable weight 5 to increase or decrease the centrifugal force of theshaft 3, and to further increase the said force the shaft 3 is equippedwith a iiywheel 6, having a poise 6, and may be further equipped by afixed Weight 7, that is keyed to the shaft 3, as shown in Fig. 2. Idesire it to be understood that while I prefer in the practicalconstruction of my machine to use the adjustable weights and the weights6a and 7 yet one or all of the said Weights may be omitted Withoutdeparting from my invenbar, fulcrumed near its forward end on thecross-bar l1, its front end forming a short leverage member 12, and itsrear end projects beyond the rear end ofthe frame 1 and terminates in ahandle 12b. The forward end of the bar 12 is bifurcated, and pivotallyhung on the extreme front end of the part 12 is a U-shaped link-bar 13.l5 designates another horizontally-disposed U-shaped linkbar, the freeends 15a of which straddle the lower end of the bar 13 and areadjustably connected with the said bar 13 by the crossbolt 14, thatpasses through the lower end of bar 13 and through any one set of aseries of apertures 15b in the ends 15a of the bar 15.

16 indicates a link member pivotally hung from the bifurcated end of thebar 12 and having its fulcrum at a point to the rear of the standards 8and at a distance equal that which the fulcrum-point of bar 13 is inadvance of the said standards 8.

The lower end of the member 16 is pivotally connected' to the rear endof an adj ustable weight-bar 17, said rear end 4being bifurcated, asclearly shown in Fig. 4. The shank portion 17a of the member 17 passesthrough the U-shaped member 13 and the standards S and has a series ofapertures 17b for adjustably pivoting the shank 17a on the cross-bar 10,(see Figs. 3 and 4,) the purpose of which is to s et the copunterpoiseor weighted member 17 to increase or diminish the balance of the saidmember 17, the function of which is to counterbalance the lever 12 andreduce the lifting force transmitted to it from the crank-shaft and thebar 15 practically to mi, requiring, as it were7 only so much force fromthe crank-shaft as is necessary to lift the member 15, and which forcemay be materially decreased by making the free end of the member 17sufficiently heavy and setting IOO its fulcrum-point so that it (themember 17) will connterbalance the members 12, 13, and 15. To furtherassistin reducing the applied force necessary-that is, the force createdby the momentum of the crank-shaft and its fly- Wheel-a buffer-spring 20is held in a socket 19, secured to the frame 1, (see Fig. 1,) whichbears against a disk 21n on the lower end of a dasher-rod 2l, pivot-allysecured to the handle member, as shown.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought the advantages and completeoperation of my invention will be readily apparent.

Ordinary manual force being applied to the lever 12 is materiallymultiplied by the correlation of the several link-bars and through themtransmitted t0 the crank-shaft. The said power can be increased ordiminished, as the character of the machine to be driven from thedrive-shaft may make desirable, by adjusting the pivotal connections ofthe several link-bars, as hereinbefore explained.

The construction of my invention is simple and of such character thatthe same may be readily put up, as the several levers andconnecting-bars can be made up by an ordinary blacksmith.

I am aware it is notvnew to provide in combination with a drive-shafthaving a fly or momentum wheel or weight and a manuallyoperatedleverintermediate link devices for increasing the leverage initially createdby I manual power, and I make no claim for such general combination; but

What I do claim as new, and for which I desireLetters Patent, is-

Thehereinbefore-described improvements in mechanical movements,comprising the following elements in combination; a supporting-frame,including the standards 2 and S, the crank-shaft journaled o'n thestandards 2, the weighted fly-wheel 6, the adjustable counterpoise 5,and the drive-pulley 4, mounted to turn with the crank-shaft, the lever12, fulcrumed on the standards 8, with its forward end 12a, projectedbeyond the Afulcrumpoint, the weighted member 17, adjustably fulcrnmedon the standards 8, its front or weighted end swinging freely, the link16, joining the rear end of the member 17, with the lever 12, the member15, pivotally hung at one end of the standards 8, a link connectionjoining the other end of the said lever l5, with thecrank-shafi, themember 13, hung pendently from the front end of lever 12, means for adjustably and pivotally connecting its lower end with the lever 15, thebufferspring 20, the dasher member 21, and the rod 21, pivotallyconnected to the lever 12, all being arranged substantially as shown andfor the purposes set forth.
